I have had PRS Dragon I's, HFS/VB, original Treble(T) and Artist II's. Compared to BK's, all of them have a 'closed' sound, where the dynamics of the strings don't come through. Also as you turn the volume down on PRS's, the tone goes off and becomes more bassy. With BK's, all the pickups remain very open as the volume is turned down. In fact this was one of the first things I noticed when I got BK's for the first time. I have currently got a Crawler & 2 P-91's in my EG4, a Rebel Yell set in my Standard 24 and an AIV Mule set in my Artist II.
The Crawler will cover all the HFS territory, and a lot more. It is a hot PAF on steroids, but can clean up beautifully. The Dragons have a ceramic bridge and alnico neck, which would be like the Cold Sweat and Miracle Man sets, though I actually like the Rebel Yell set as a replacement.
I did have VHII's in my Artist for a while, and they are great pickups but I wanted a bit more bluesy sound and went for the Mules. You don't mention what style of music you play, but the VHII is very versatile, covering everything from metal to classic rock.
